Description

  The present invention relates to a method for forming a rough surface of a surface of a molded body that roughens the surface of a solid molded body.

As a method for roughening the surface of a solid molded body made of glass, resin, or metal to form a matte surface or a satin surface, hard solid particles such as metal coarse particles, sand, and abrasives are molded. The sand blasting method that sprays on the surface of the body is well known.
However, this sandblasting method requires a device for spraying solid particles such as the metal coarse particles, sand, and abrasives onto the molded body, and a measure for preventing the solid particles such as metal coarse particles, sand, and abrasives from being scattered. . In the case of displaying a pattern such as a figure, a letter, or a symbol on the surface of a transparent molded body such as glass or resin, or on the glossy surface of a metallic molded body by a matte surface or a satin surface. As disclosed in Japanese Patent No. -52899, it is necessary to mount a pattern from which a figure, a character, or a symbol to be displayed is cut out on the surface of the molded body in advance. Therefore, this sandblasting method is suitable for mass production of solid molded bodies made of glass, resin, or metal in factories, but for example, repairing the satin finish of metallic molded bodies that have become glossy due to damage. Therefore, it is not suitable for forming a small rough surface.

Furthermore, considering the prevention of scattering of solid particles such as the above-mentioned metal coarse particles, sand, and abrasives, the sand blasting method is preferably carried out in a sealed container or a room provided with anti-scattering measures. There is a limit to the size of the molded body on which the surface and satin can be formed. Therefore, the rough surface of a large molded body is rubbed with an abrasive or corroded with an acid, or a method in which a material on which a rough surface has been formed in advance is processed into a molded body. In particular, a stainless steel molded body having a satin finish on its surface is often made by processing a stainless steel plate (2B finish) on which a satin finish has been formed in advance. Japanese Patent No. 147900 discloses a surface shape adjustment method in which stainless steel is annealed in an oxidizing atmosphere and then subjected to electrolytic pickling to finish it to a whitish matte surface.
However, when processing a metal plate, especially a stainless steel plate (2B finish), on which a satin finish has been formed in advance to make a molded body, the surrounding satin finish is polished by polishing the portion after cutting or welding. Or part of the satin surface may become glossy due to the pressing force applied by the contact between tools or materials. Even if the mirror-finished or glossy surface has a small area, it must be treated as a defective product depending on the product. In particular, a large product has a large loss and cannot be ignored. Therefore, whether or not the mirrored or glossy part can be repaired depends on the product price, but conventional matte surface forming methods such as sandblasting and oxidation annealing have special equipment. Even if you ask a factory that has the equipment, you will be entrusted and transported, and you will not be able to expect the cost reduction effect. For this reason, until now there is no means to restore the glossy 2B finish to a matte surface, and when processing the 2B finish, the polished part after cutting or welding should be made as small as possible or 2B It was necessary to work with great care so as not to bring the tool into contact with the surface of the finishing material or between the materials.
